COATING NOZZLE, COATING DEVICE HAVING SAME, AND COATING METHOD THEREOF

摘要

Disclosed is a coating nozzle combining a left half and a right half; the mating surface of at least one of the left and right halves is formed with a recess determining the width of a slit-type outlet; two ends of the coating nozzle are provided with side plates, the side plates enclosing a side opening formed by the recess; the mating surface of the half having the recess is fixedly provided with N barriers; the N barriers divide the recess so as to divide the coating nozzle into N+1 independent sub coating nozzles, N being a positive integer. The coating nozzle is a coating nozzle having a large lateral dimension and being divided into a plurality of sub coating nozzles having smaller lateral dimensions. When the movement of the coating nozzle is accelerating or decelerating, each sub coating nozzle sprays coating liquid with good uniformity from the center and two ends of the outlet thereof. Also disclosed are a coating device having the coating nozzle and coating method thereof.
